    Third Quarter Highlights

    --  Serena and Silver Lake Partners, the leading private equity
        firm focused exclusively on large-scale investing in
        technology and related growth industries, announced that they
        have entered into a definitive agreement under which Serena
        will be acquired by Silver Lake in a transaction valued at
        approximately $1.2 billion. Under the terms of the agreement,
        Serena stockholders will receive $24.00 in cash in exchange
        for each share of stock. Any of Serena's existing $220 million
        of convertible notes that are not converted to Serena common
        stock prior to completion of the proposed transaction will be
        exchanged for cash in an amount of $24.00 for each share of
        Serena common stock into which the notes were convertible.
        Douglas D. Troxel, founder of Serena and currently its
        chairman and largest shareholder, will receive $24.00 per
        share in cash in exchange for one-third of his shares and will
        exchange the balance of his equity interest in Serena for
        shares in the resulting privately held company. Serena
        president and chief executive officer Mark Woodward, chief
        financial officer Robert Pender, and possibly other senior
        executives will also exchange a portion of their Serena equity
        interests for equity interests in the resulting privately held
        company.

        Both the board of directors of Serena and a special committee
        of the board comprised of independent directors have approved
        the merger agreement and have recommended to Serena's
        stockholders that they vote in favor of the transaction. In
        addition, Mr. Troxel has agreed to vote his shares in favor of
        the transaction.

        more effectively govern change.

    GAAP to non-GAAP Reconciliation

    Serena management evaluates and makes operating decisions using
various operating measures. These measures are generally based on the
revenues of its product, maintenance and services operations and
certain costs of these operations, such as cost of revenues, research
and development, sales and marketing and general and administrative
expenses. Such measures include non-GAAP net income and non-GAAP net
income per share. Collectively, we refer to these non-GAAP financial
measures as "non-GAAP measures." We have outlined below the type and
scope of the amounts excluded in calculating these non-GAAP measures
and the limitations on the use of these non-GAAP measures as a result
of these exclusions. These non-GAAP measures are not an alternative to
net income as calculated in accordance with GAAP. Investors and
potential investors in our securities should not rely on the use of
these non-GAAP measures as a substitute for any GAAP financial
measure. In addition, our calculation of these non-GAAP measures may
or may not be consistent with that of other companies. We strongly
urge investors and potential investors to review the reconciliations
to the comparable GAAP financial measures that are included below and
not to rely on any single financial measure to evaluate our business.
    Serena views non-GAAP net income and non-GAAP earnings per share
as operating performance measures, and as such it believes that the
GAAP financial measures most directly comparable to them are net
income and net income per share, respectively. Non-GAAP net income and
net income per share differ from comparable GAAP measures in that they
exclude the amortization of intangible assets and charges relating to
the purchase accounting adjustments for the acquisition of Merant,
amortization of acquired technology and intangible assets, stock based
compensation, restructuring, acquisition and other charges.
    Management believes it is useful in measuring Serena's operations
to exclude amortization of intangible assets and charges relating to
the purchase accounting adjustments for the acquisition of Merant
because these costs are primarily fixed at the time of the acquisition
and generally cannot be changed by management in the short term, or
represent significant costs not related to current operations.
Non-GAAP net income and non-GAAP earnings per share are helpful in
highlighting trends in its core business that may not otherwise be
apparent when relying solely on GAAP financial measures, because these
non-GAAP measures eliminate from net income financial items that have
less bearing on Serena's operating performance. The Merant acquisition
was a particularly large acquisition in Serena's history, and
management believes the impact of charges relating to the acquisition
can make it more difficult to evaluate the trends of Serena's
underlying business, including the performance of its products,
maintenance and services operations. Serena believes it is useful to
investors to see how management separates initial transaction costs
from its view of Serena's current and future continuing operations.
Management also believes that these non-GAAP measures facilitate
comparison of the current operating performance of the combined Serena
and Merant operations to the past performance of Serena and Merant as
separate companies, as it permits the comparison of operating results
of the separate companies, viewed together, to Serena's current
operating results without the impact of charges relating to the
acquisition process rather than the underlying operations of the two
companies.
    Serena's management uses these non-GAAP measures as supplemental
financial measures to evaluate the performance of Serena's business
because, when viewed with Serena's GAAP results and the accompanying
reconciliations, it believes they provide a more complete
understanding of factors and trends affecting its business than GAAP
results alone. Serena uses these measures to make forecasting,
budgeting and operating decisions such as establishment of operating
targets, budgets and bonus compensation.
    Serena communicates these non-GAAP measures to the public through
its earnings releases because we understand that they are financial
measures commonly used by analysts that cover our industry and our
investor base to evaluate our performance. For example, based on
communications with analysts and investors, Serena understands that
some analysts and investors may value companies based on a measure of
discounted future cash flows and that Serena's non-GAAP financial
measures can be useful to such analysts in performing such valuations.
Management believes that presenting these non-GAAP measures provides
investors and analysts with an additional base line for assessing the
future earnings potential of Serena. Serena prefers to allow investors
to have these supplemental measures since, with reconciliation to
GAAP; they may provide additional insight into its financial results.
    Non-GAAP measures should not be considered a substitute for
measures of financial performance prepared in accordance with GAAP.
Investors are encouraged to look at GAAP results as the best measure
of financial performance. For example, amortization of acquired
technology and intangible assets are important to consider because
they may represent initial expenditures that under GAAP are reported
across future fiscal periods. Stock based compensation and
restructuring and acquisition related charges are important because
they may represent obligations of Serena that should be considered.
All of these metrics are important to financial performance generally.
Investors and potential investors are encouraged to review the
reconciliation of non-GAAP financial measures contained within this
press release with their most directly comparable GAAP financial
results.
    Though Serena management finds its non-GAAP measures useful in
evaluating the performance of its business, its reliance on these
measures is limited because items excluded from such measures often
have a material effect on its net income and net income per share
calculated in accordance with GAAP. Management compensates for the
above-described limitations of using a non-GAAP measure by using these
non-GAAP measures to supplement Serena's GAAP results to provide a
more complete understanding of the factors and trends affecting our
business.

    This press release contains "forward-looking statements" under the
Private Securities Reform Act of 1995. There can be no assurance that
future results will be achieved, and actual results could differ
materially from forecasts and estimates. Factors that could cause or
contribute to such differences include, but are not limited to, the
percentage of license revenue typically closed at the end of each
quarter making estimation of operating results prior to the end of the
quarter extremely uncertain; weak economic conditions worldwide which
may continue to affect the overall demand for software and services,
which has resulted in and could continue to result in decreased
revenues or lower revenue growth rates; our ability to successfully
integrate our acquisition of Merant plc.; changes in revenue mix and
seasonality; dependence on revenues from our installed base; the
expansion of our international organizations; continued demand for
additional mainframe MIPS capacity; our ability to complete the
assessment of internal controls over financial reporting as of January
31, 2006, as required by Section 404 of the Sarbanes-Oxley Act, which
may impact market perception of the reliability of our internal
controls over financial reporting and thus adversely affect the market
price of our common stock; and our ability to manage our growth. We
may not be able to complete the proposed transaction on the terms
summarized above or other acceptable terms, or at all, due to a number
of factors, including the failure to obtain approval of our
stockholders, regulatory approvals or to satisfy other customary
closing conditions. Information about potential factors that could
affect the Company's financial results is included in the Company's
Form 10-K filed on April 8, 2005 and Form 10-Q filed on September 9,
2005. Serena assumes no obligation to update the forward-looking
